A 33-year-old Asian male presented with spontaneous nosebleeds and olfactory sense problems for the past several years. CT scan and MRI demonstrated a large soft tissue mass in the nasal cavity and paranasal sinus with avid and homogeneous contrast enhancement, focal osseous destruction and a non-enhancing cyst at the intracranial tumour-brain margin. After complete endonasal resection, histopathological examination revealed a paraganglioma. This case highlights the non-specific imaging features of a rare paraganglioma of the anterior skull base and the differential diagnosis from both radiological and pathological perspective.
一名33岁的亚洲男性在过去几年中出现了自发性鼻出血和嗅觉问题。CT扫描和MRI显示鼻腔和鼻窦有一个大的软组织肿块,造影剂呈强烈且均匀的增强,有局灶性骨质破坏,且在颅内肿瘤-脑边缘有一个无强化的囊肿。经鼻内镜完全切除后,组织病理学检查显示为副神经节瘤。该病例突出了罕见的前颅底副神经节瘤的非特异性影像学特征以及从放射学和病理学角度的鉴别诊断。
